7 simple steps that ACTUALLY MATTER to building a winning pinewood derby car. I built a car in 45 minutes using these steps and crushed all the competition by more than 2 car lengths (proof is in the video :) Special thanks to Steve at DerbyMonkey.com for providing his expertise and materials for the video.

HERE'S HOW I MADE THE ROCKET CAR: automobilrevue.net/v/dmxCeFBqeGFjc2s

7 Key Steps:
1. Max weight ~1" in front of rear axle
2. Reasonably aerodynamic
3. Ride on 3 wheels
4. Lightweight wheels
5. Bent polished axles
6. Railride/alignment
7. Lots o' graphite

      I built a Kubkar for my stepson and it absolutely dominated I actually felt bad for the other kids it would hit the backstop as some cars crossed the finish line. It didn't ride the rails and tracked dead straight.

      1. Polished wheels/axles by holding wheels against an upside down RC car run at highspeed prior to install

      2. Dry graphite on axles

      3. Used a credit card as a spacer to achieve equal gaps between the body when installing wheels and a flat head screwdriver to ensure axles were fully seated in slot and square all around - drop of JB weld to secure

      4. Glued pennies to rear bottom over the axle slots

      5. Had stepson paint it so he could take the credit

      Great video. I think you did a fantastic job explaining the science behind it all and summing up the research. With that being said, I followed the major steps (except for nail polishing) and both cars never did better than second out of 8 heats. Our track was a straight angle. There really was no drop. Would that affect things? If so, how? Thanks again.

      Good thing this is a CUB SCOUT event. Immediately after the event the kids take the cars and play smash em up with them. These are Elementary school kids. Please let them have fun.

      You probably have answered this already. How do you get the right hand in the axles without a tool. What is the length of the straight before the bend. What is the final angle?

      Built my daughter’s car exactly as said, super fast, would probably win, find out when you arrive at the derby that GSA does not allow canting or bending whatsoever of the nails...... Ugh. So, I guess rules are different between what was BSA and GSA? Annoyed.
